I'm not sure is this bug or what but my elven army once disappeared and never appeared again. I was transferring my units back to village. My resources are disappearing too fast and I can't build towers (I have already researched all engineering technology). Even palisade won't disappear when I build my stonewalls and one stonegate disappeared when I tried upgrade it to Archway (or whatever it was). I have problems with garviolas too. They always disappear once I log out and then log in. With orcs I have problem too. My labourers stop working when I log in and I have to give them something to do again. There is also sometimes yellow light what fills whole area but it disappear when I exit game and start again. I almost forget that I can't find any PvP players or make Alliance. I get message that can't connect to servers. I can't play Kindom Wars either.
